Features
AI super-resolution up to 16×
Bigjpg uses deep convolutional neural networks to enlarge images up to 16× while reconstructing lines, colors and fine details.
Artwork and photo focus
The tool is built for artwork and photos, aiming for sharper lines and cleaner images with less noise after enlargement.
Batch and parallel enlarging
Paid plans add batch mode, parallel enlarging and offline enlarging for processing multiple images in one session.
Upload limits
Files can be up to 50MB and 3000x3000px, while the free plan caps uploads at 5MB and enlarging at 4×.
Enlarging history
An enlarging history lists past jobs with options to delete, download or retry each result, though only the last day's records are shown.
What users say
Pros
- Free-tier upscales come out with almost no artifacts and very little lost detail.
- Repeated upscaling jobs work well on the free tier without buying a paid plan.
Cons
- The interface is not in English, so setting labels and options take guesswork.
